Answer:
The trip with less acceleration has it when the radius is smaller, for which Gertrude is right
Explanation:
We will propose the solution of this exercise, with the second law of / newton
F = m a
where the acceleration is centripetal, whose equation is
a = v² / r
where v is the linear speed of the chair and r is its radius from the turning point.
Acceleration depends on the two parameters: linear speed and radius, for which reason we must take them into account for an analysis.
angular and linear speeds are related
v = w r
therefore we see that the linear speed also changes with the radius, but the angular speed is constant for the entire apparatus; let's substitute to see which variable is more important
a = (w r)² / r
a = w² r
Since the angular velocity is constant, the relationship dependency is linear with the radius.
The trip with less acceleration has it when the radius is smaller, for which Gertrude is right
Bernice's problem is that it does not take into account that the acceleration depends on the two parameters linear speed and radius
The perspective which best explain this is SOCIO-CULTURAL PERSPECTIVE.
Socio-cultural perspective is a theory which explains the awareness of situations surrounding people and how their behavior is determined by their environment, culture and social values.
The speeds and velcity will be 0.020 m/sec and 0.0149 m/sec.
<h3>What is speed?</h3>
Speed is defined as the rate of change of the distance or the height attained. it is a time-based quantity. it is denoted by u for the initial speed while V for the final speed. its si unit is m/sec.
Given data;
d1=50 m E
d2=95 m N
Time period,t = 12 min = 12 × 60 sec = 7200 sec
The displacement is the shortest distance found from the pythogorous theorem as;
Displacement = √[(50 )²+(95)²]
Displacement = 107.35 m
a)The speed is found as;
Speed = distance / time
Speed = 50 +95 / 7200
Speed = 0.020 m/sec
b)The velocity is found as;
Velocity = Displacement / time
Velocity = 107.35 / 7200
Velocity = 0.0149 m/sec
Hence the speed and the velcity will be 0.020 m/sec and 0.0149 m/sec.
